Downhole

Observation and Production Well Assemblies (MI cable)These well assemblies are constructed completely with high temperature single, duplex or triplex MI cable with special high pressure sealing collars (transitions). They may be manufactured with different sheath materials (316SS, Inconel 600, Incoloy 825).

WIKA has perfected the process of manufacturing downhole thermocouples year round while

maintaining ideal conditions. We are capable of manufacturing downholes greater than 5 kilo-

meters in length and with up to 60 points. Special high pressure transitions are used to achieve

desired lengths without jeopardizing quality or durability. Steel crimp rings are utilized to bundle

multiple sensing strings prior to installation.

WIKA has manufactured downhole thermocouples to suit the following applications:

� Coil Tube

� Pump-in

� Clamped to production tubing

� Clamped to casing
